Title: Pixel driver for an organic electroluminescent device
Inventor: TAM SIMON
IPC: G09G3/32
Filed: 2000-07-07
Abstract: A compensated pixel driver circuit for an organic electroluminescent device, the circuit comprising; a transistor connected so as operatively to control the current supplied to the electroluminescent device, a capacitor connected for storing an operating voltage of the transistor during a programming stage, a first switching means connected so as to establish when operative a current path through the transistor during the programming stage, and a second switching means connected so as to establish when operative a current path though the transistor and the electroluminescent device during a reproduction stage, wherein the first switching means is connected such that the current path during the programming stage does not pass through the electroluminescent device. No current is applied to the electroluminescent device by the current controlling transistor during the programming stage and thus the overall power consumption is reduced. Furthermore, the circuit can be operated from a normal supply voltage rather than requiring a high bias voltage. During the programming stage, the circuit uses a current sink rather than a current source.

Title: Drill bit
Inventor: MENSA-WILMOT GRAHAM
IPC: E21B10/56
Filed: 1997-09-23
Abstract: A fixed cutter drill bit has rows of cutter elements C<SB>1</SB>-C<SB>20</SB> arranged so that the cutting tips of the cutters C<SB>1</SB>-C<SB>20</SB> in a row are disposed at leading and lagging angular positions so as to define a serrated cutting edge. The angular position of the cutting tips of cutters C<SB>1</SB>-C<SB>20</SB> in a given row may be varied by mounting cutters with different degrees of positive and negative backrake along the same blade B<SB>1</SB>-B<SB>4</SB>. Preferably, within a segment of a given row, the cutters C<SB>1</SB>-C<SB>20</SB> alternate between having positive backrake and negative backrake while the cutters mounted with positive backrake are more exposed to the formation material than those mounted with negative backrake. The positive backrake cutters have a dual-radiused cutting face 44. In a main claim, a row includes a first and a third cutter element mounted with cutting faces having a positive backrake angle and a second cutter element mounted with a cutting face having a negative backrake angle, the second cutter element being mounted in the row between the first and third cuter elements.

Title: Identification and location sensor
Inventor: WOODHAM RICHARD GEOFFREY
IPC: G01V3/08
Filed: 2001-01-17
Abstract: Method and apparatus for identifying and locating items, in particular playing pieces for board games, comprises a board consisting of multiple locations each of which comprise insulated conductive tracks (5, 6, 7) in which one track (5) is excited with an alternating electric signal and the other tracks (6, 7) are connected to sensing circuits. The pieces have flat insulating bases with conductive patterns thereon which overlay the conductive tracks when placed at a location, and resistive elements (8) whose values determine the identity of the piece. The location of a piece is determined by the sequential excitation of the transmitting tracks over multiple locations and sensing of magnitudes of received signals, whilst piece identification is achieved by measuring the magnitude and phase of the received complex impedance signal which is unique to each piece. Single frequency excitation is disclosed although a range of frequencies may be used, and capacitive, inductive or resonant elements may also be used with the resistive elements.

Title: Flow path for a liquid cooled alternator
Inventor: LINDEN DAVID WILLIAM
IPC: H02K9/19
Filed: 2002-12-16
Abstract: An alternator includes an inner housing and an outer housing. A pair of o-rings positioned therebetween create a sealed flow chamber having a first flow channel, a second flow channel and an axial passageway. The first flow channel is a disk shaped cavity extending diametrically across the alternator. The second flow channel forms an annular jacket extending entirely around the alternator. The axial passageway directs coolant axially from the first flow channel into the second flow channel. An inlet positioned diametrically across from the axial passageway allows coolant to enter the first flow channel, such that coolant entering the inlet must flow diametrically across the alternator to reach the axial passageway. An outlet positioned diametrically across from the axial passageway allows coolant to exit the flow chamber, such that coolant entering the second flow channel must travel annularly around the alternator to reach the outlet.
